The SIESTA recording protocol

A major task of SIESTA was the recording of a large normative data base of both healthy subjects and patients with sleep disturbances of disorders affecting their sleep. The aim was to record data from 200 normals across all age groups from 20 to over 80, two nights each, and data from up to 100 subjects with disorders from one of the following groups: Data records should consist of two polygraphic all-night records, results from clinical examination, results from questionnaires and psychphysic tests, and data from 14 days of actigraphy. The main motivations in setting up the protocol were: Of course, the variety of signal and other information is limited to the common denominator of a large group of different sleep labs, in terms of number of channels they can record and in terms of time available for tests and examinations. This is why the protocol specifies a minimum obligatory setting but provides room for optional additional channels and procedures.

The recording task of SIESTA (which is otherwise sponsored by the EU commission, DG XII), in particular the recording of actigraphic data, was supported by Cambridge Neurotechnology.
